40% =
40100 =
25 Min spent: Min's total = 2 : 5
Amount that Zara spent
= 2 x 2 u
= 4 u
Amount that the three girls spent
= 2 u + 4 u + 298
= 6 u + 298
Amount that the three girls spent
= 1472 - 730
= $742
6 u + 298 = 742
6 u = 742 - 298
6 u = 444
1 u = 444 ÷ 6 = 74
Amount that Olivia and Zara had in the end
= 730 - 3 u
= 730 - 3 x 74
= 730 - 222
= $508
Answer(s): $508
